Engine build - exhaust

[Challenger340]

Sorry I was not able to make it Mitch, I am still pretty sick, wish they would have had afr reading & try to address the valvetrain  issues, noise ect, that motor will make more power if that problem was fixed, & jetting of the carb, even where its at now it will scare the crap out of you.

I agree Charlie.... LOTS left in that Engine !     nonetheless, it will still rock as is.

Hope your feeling better soon.

Good to hear from you, Charlie.  I had lots of fun. 

Yes valve train issues with these heads.  If I wanted to do anything over 5000 RPM, there would need to be some work done, probably springs.  They asked if I wanted to tear the head down again and add higher rate springs.  I declined.  Also, every time they upped the coolant temp the engine got quieter so we'll see what happens in a Houston summer.  The oil was still the break in oil.  For me, it's going to be fine for a while.  I'll be able to get Charlie to help with final tuning, not many folks out there that can tune a carburated car today. 

I'm happy with it as  first step.

I am about ready to buy the rockers for my 440 to 505 build. I have recently learned something that may help you. I am using a hydraulic roller cam and Harland Sharp roller rockers. Using the Trick Flow PP240 heads. Harland Sharp rockers are listed for big block mopar, BUT, they list the same part number except it has an E after it if using with Edelbrock or Trick Flow heads. I called in to Mancini this morning and asked about that. Mancini told me a customer was using the standard big block Mopar roller rockers with Eddy heads and had trouble, HS made a revised rocker for the Eddy and TF heads, put an E at the end of the part number. The revised rocker is what I must use.

Any one have better info?

Its the distance between the the rocker shaft center line and valve center line being slightly different from the factory head.  Really not that big of a deal. Using one on the other would not cause anything like what the OP is experiencing.

As far as the comment about the valve train going away at 4700, that seems a little low to me.  I think the cam and springs are done at 5000, and then depending on everything else, I might get another 100 or 200 RPM out of it, but it's not worth anything and things are falling off fairly fast at that point.  Looking at the graphs (sorry I didn't get them printed out) everything was really smooth and even, various runs had small changes but they laid on top of each other fairly close.  Yes, the timing changes made a few HP here and there but nothing to get excited about.  I am disappointed that they did not use a AFR meter. 

We did have a discussion on the next step.  Given that the pulls were done with different headers and out of the car, the guys said that anything beyond what we tested  may be wasted effort.  Get the engine in the car, mount the headers and then see what can be done.  That's where CDR will come in.  But in the end, 10 more HP may not make much diff in how it feels in the seat of my pants.

Right now the spark plugs looked really good, idle was smooth and the pulls were nice and even up to 5000 RPM.  And 540 ftlbs of torque!!  That seems like a gob!

Final comment.  The valve float at high RPM was distinctly different when we changed the coolant temp from 155 (noisy) to 165 to 180 (quietest).  Could it be that the lifters were the problem because of the changing viscosity of the oil?

Do you by chance know what the installed V/Spring Pressure and rate was ? as it was run on the Dyno ?

Than you Bob The Machine shop should know, we had them take the heads apart, back cut intake valves, check & reassemble them.

I think this is right.  Measured at 125 on the seat, 305 at max lift(0.6).  I'll confirm.  My cam is .488/.491.

171.00 for a starter?  What did they sell you?

[firefighter3931]

Those are very nice numbers for a mild street build. It'll be a blast to drive with all that bottom end power. 

Instant tire smoke at 1/2 throttle 

Good job guys !

Not quite the end of the story.  After talking to the machine shop and Charlie, the shop added .060 shims under the springs (expect to add about 25 lbs pressure,)  Jeff (machine shop owner) recommended to get away from the valve float problem.  No more dyno runs because they already took it off the stand so we won't know anything till it is in the car and we fire it up.  Given the way I drive, the shims will be enough improvement that I'll be satisfied.  Just for info, the springs on the estreet head are really low pressure, according to Edlebrock the spring pressure is only 280 at .480 lift, 138 on the seat.  Maybe not the best setup for a XE cam...

Not my smartest choice.  It was a PowerMaster starter from Summit.  Nice thing about it is that the terminals easily cleared the block.

It's now a used part, no returns.  But that is an interesting solution.

Just teasing ya!

Well, dang!  Now I have to get down off my hi horse.  ( still a neat solution.)

This looks great!!

Pic #1,2,3 Transmission arrived and in garage.
Pic #4 Trans in the car ready for converter and engine.
Pic #5 engine bolted up to trans,  and motor mounts, headers in

Got to say, putting those headers in was a pain.  Biggest problem was the driver side.  Turns out the header is directly blocking the long bolt that attaches the mount to the k frame.  No way to bolt the mount to the engine and then bolt to k frame.  Two options, leave the header in place but dangling free while bolting up the mounts then bolt down the header.   Or, bolt mount to the k frame, install engine and then bolt mount to engine.  TTI recommends first method and it worked.  

Edit: before I forget...the bolts for the motor mount are different for my 76 block vs the old 69 383 block.  a couple of the ears that are on the block are thicker and require a longer bolt.

   AWESOMENESS !!! 

[green69rt]

If nothing else, it is pretty.  Getting the trans cross member in today.  Had to stop while the bolts cool down from RPM treatment.

Looking good SIR!

Where did you get the SS thermostat housing from?
Motor looks sharp.
